BY HIS ATTORNEY g Patented Oct. 4, 1932 UNITED STATES PATENT j oFFIcEEDWARD BLOOM, OF IPATERS O N, NEW' JERSEY I Applicatiohfiled Iarch 19,1932. Serial No. 599,901. i '1 This invention relates to that type ofshuttlei'in which the spindle is pivoted on a transverse axis so that itmay be elevated in order to replace the'weft package when exhausted.Usually the spindle is pivoted r on one pin and has its pivotal movementlimitedby another pin, and a rebent plate spring, acting on the spindle,is supported by two otherpins, all four pins penetrating the sidesof theshuttle body. In consequence these pins not only work out and causeserious damage to the warp but they give rise to splitting of theshuttle body.

" One object ofthe present invention is to eliminate these several pinsand avoid the faults to which they give rise. Another ob- ;ject is toprovide a wound-package-supporting assembly comprising, with a housinghaving a pivot-afiording means, a spindle pivoted in said housing andwhich assembly shall be removably secured in the shuttle body in asimplyeii'ected' and secure manner.

In the drawing, Fig. 1 is a plan of a shuttle embodying this invention;

Fig. 2 is a longitudinal substantially central vertical section thereof,with the spindle in side elevation;

Fig. 3 shows the spindle and itsmounting in side elevation;

' Fig. 4 is a section on line 4-4, Fig. 2';

Fig. 5is a section on line 5-5, Fig. 3; and Fig. 6 shows the blank fromwhich the housing portion'of the mounting is formed, this view being ona smaller scale.

The shuttle body 1 has the usual cavity 2 for the wound package, thesame at one end terminating in a reduced extension 2a provided with abottom and two top overhangs or top flanges 2b and which I thereforeterm a mortise; the outer'lend of this mortise is preferably inclined(Fig. 2).

The spindle mounting is formed as follows 3 is a housing for the spindlebutt formed from the blank shown in Fig. 6 which is a piece of sheetmetal having two lateral wings 36; that are bent up perpendicular to itsmidportion 36 and an end portion 30, that is bent up obliquely to meetthe adjoining oblique edges of such wings the housing thus has twospindle proper becomes deformed it may thus bottom of the housing tolimit the depress- 5. Wall 30 also has a hole 6. The holes at receive apivot pin 11,'to be referred to; if desired theends of this pin may beupset or riveted to prevent it from endwise displacement, although whenthe mounting is in W5 place in the mortise the sides of the latter willprevent it from such displacement. When the mounting is in place in themortise it is held therein by a screw 7 driven through C itshole 6 intothe wood of the shuttle body. 85

' The fixed structure of the shuttle may be regarded as comprising thebody 1 and m0unt- 'ing, the cavity 2 extending into the mountingwhen'the latter is in place.

The spindle is here formed in three parts thespindle proper 8, the butt9 into which thespindle proper is screwed, and a lock-nut 1O screwed onthe threaded end of the spindle and jammed against the butt. If thebereadily removed for straightening. The butt 9 is a blockfitting snuglybetween the plates 3a of the housing and having bottom faces 9a'and 96adapted to'bear against the ing and elevating movements, respectively,of the spindle. It has a hole to receive the mentioned pivot pin 11.Registering with the holes 5 of thehousing when the spin- 1 dle isdepressed the butt also has two transverse bores 12 these are opentoward the respective plates 3a but at their other ends they areclosed.Each bore'contains a plunger 13 and a spring'l i, the latter holding theplung-.

er againstthe corresponding plate. Each 90 purposely elevated, manually.The elevation of the spindle is limited, by contact of its butt face 9?;with the bottom of the housing, so

1 that the plungers may not escape unless the r pin 11 has first beenremoved. One plunger would serve but two, disalined with each other, arepreferred so that adequate spr ng power maybe had) within thenarrowllimit afforded by the butt.

By my construction no part of the mount ing for the spindle is. capableof. becoming detached and falling away from the shuttle} V The onlyelement that is not positivelycon fined is 7, but since this is a screw.driveniinto i the wood of the body itis notjlikely to start to workout,and even if it should such would be noted by the Weaver orloom-fixer before the screw became entirely free, The'plungers andspringsare permanentlyconfined by the flanking portions of the fixedshuttle struc- .ture so long asthe mounting is in. the shuttlebecausethey are never ireed except when the pivotll has been-Iremovedand movement of the spindle beyond the limits'normally at 7 v 1 fordedby the. contact of one or the other of the butt faces9a and 9b with thebottom of the housing is then possible. v 'Having thus fullyjdescribedmy inventlon ,What I claim isz".
